The Co-Doping Effect of Si and Mn on the Dilute Ferromagnetic Semiconductor Thin Films
The co-doping effect of Si and Mn have been studied in the low temperature grown ferromagnetic semiconductor (Ga,Mn)As thin films. It is found that Si doping decreases the Curie temperatures of the ferromagnetic sample due to carrier compensation and defects formation. The transport studies show that the Si incorporation increases the resistivity of the (Ga,Mn)As thin films, and increase the planar Hall resistance while increases the resistance transitions in the magnetic samples.
